acids-bases questions
« on: June 18, 2007, 01:20:47 PM »
1/
A weak acid (HX) has an equilibrium constant of K. what is the PH of a 1 M solution of this acid

2/
how do we know if a compound when dissolved will be an acid or base ? for example K2CO3

3/
1 molal solution of magnesium chloride has a higher boiling point than 1 molal solution of solution of ( a: FeCl3   b: CaCl2  c: BaCl2  d: NaCl )   explain why

4/
explain why a water solution of KCl would have a PH closest to 7

5/
one liter of 1M NaOH will completely neutralize one liter of ( a: 1M H2SO4  b: 0.5M H2SO4 )

6/
which metal will react spontaneously with HCl  (Au ; Ag ; Cu or Mg) explain why

7/
Does the PH of an aqueous solution of an organic compound always equal to 7 ?

8/
which of the following acids ionizes to the least extent at 25°C ? (HF ; HNO2; H2S; H2O) explain why
